WebAns :The best application of spatial coherence is in lasers that are used in holographic imaging. Holographic images produce a three-dimensional wavefront image of an object. For this purpose, lasers are used as they exhibit high spatial and temporal coherence. This increases the clarity of the images produced. But it also increases its cost. WebA single-transverse-mode Q-switched Nd-glass laser, which can operate over a number of longitudinal modes variable from 1 to 100, has been used to investigate laser temporal …
